re: #4

Watch out for a few things:

1. Refreshes are much slower on 3-color eInk panels than on monochrome ones (eg: 20 sec vs 2)

2. Partial refresh on 3-color panels is rare and quickly gets messy around the edges. Partial refresh on monochrome panels is a relatively simple thing to do.

3. Greyscale on a 3-color eInk screen is VERY VERY VERY hard! Officially it is not supported at all. By any 3-color panel. I made it work [1] but even then, it is very very slow (bordering on a full minute per refresh).

4. Stock waveforms are rarely good. And almost no vendor will give you proper temp-compensated partial update waveforms. Developing your own waveforms for monochrome panels is easy and simple (~day). Developing your own waveforms for 3-color panels is a lot of work (~weeks + more weeks once you need to support more than just "21-25 celsius")
